' displays effective whether or not illuminated.

This invention has utility when incorporated in collapsible shadow boxframes, even enclosed and metallic against fire hazard.

Referring to the drawing:

Fig. 1 is a front elevation of an embodiment of the invention in theportable sign hereunder;

Fig. 2 is an end elevation from the right of the sign of Fig. 1;

Fig. 3 is a distributed view of the sign of Fig. 1 with the insertdisplay as partially in position and the closure frame section therefor;

Fig. 4 is a section on the line IV-IV, Fig. 1, showing the light inenclosed position in the assembly;

Fig. 5 is a View of the collapsed wings as to the frame from the rear;

Fig. 6 is a section on the line VI-VI, Fig. 4, showing the interlock forcooperation between the free ends of the wings from the frame; and

Fig. '7 is an elevation of the back closure or cap to complete theshadow boX.

Electric conductors I, 2, in conduit 3 lead to xture 4 having insulationrings 5 at mounting opening 6 in back I for the electric incandescentlight 8. 'This back 'I is shown as having marginal flanges 9, I0,coacting with free ends of the wings II, I2, I3, I4. Each oi these wingshas on the fourth edge an aligned series of ventilation openings I5 withspacing I6 therebetween as an effective hinge located by these openings.

Integral with the wings I I, I2, is frame side I'I having front framestiiiening portion I8 therealong and spot welded therewith. Wings I3,I4, have integralextensions I9 forming a front of connecting frame piecewith back stiffening portion 20 between the Wing portions Il. There is asubstantial rectangular frame having opening 2|. This frame base isbounded on three sides by trim 22 having an inwardly directed flange 23.Opposed thereto i s ange 24 weld anchored with the back of the frameproper. Between the flange 23 and the main frame is a clearance in whichmay be inserted display panel 25, say of glass having selected indiciaor advertising 2B. As such transparency or partial transparency ortranslucency be thrust into position, the supplemental frame side 2l(Fig. 5) may be slipped into cooperation with springs tongues 28 incompleting the trim for the display. These tongues or lugs 28 are spotwelded with the frame side 20 to overhang the side 2l. The sign isaccordingly one in which the substitutive disclosures may be readilyinserted and replaced independently of any change in the set-up or lightposition, whether the light be out, continuous or flashing.

An advantage hereunder has to do with the compact shape in which thisdevice, say as made (Cl. l0-132) in such circumstances the hinge meansI6 allow the several wings to be collapsed or lie iiat against the mainframe. For setting up, it is in order to spread the wings II, I2, intoapproximate parallelism away from the frame. The sides I3, I4, arebrought out but still have a converging direction, and arc shapedoffsets 29 from these converging sides I3, I4 (Fig. 6), adjacent thefree end cooperate with complementary arc-shaped offsets 30 in the wingsII, I2. There is thus an effective and stiii interlocking of this sheetmetal reproof set-up. As this snug form is provided, the back I may besnapped into position to close this portion between the wings, to whichend the flanges 9 snugly rest against the free ends of the sides I3, I4.Flanges I il have arc-shaped offsets 3| coacting with complementaryarc-shaped flange offsets 32 of the wings II, I2, and this snapping ofthe back l is accordingly in a snug holding position against casualshifting. This means that there is a substantial set-up of re safetyprovision.

What is claimed and it is desired to secure by Letters Patent is:

1. For a translucency, a frame, a pair of wings converging therefrom, anadditional pair of wings spaced by the converging wings, each of saidwings being integral with a side of the frame, and a separate backproviding a mounting for a light to be directed toward the frame, therebeing iianged holding means between the edges of the back and the edgesof the wings forming a nested assembly.

2. For a translucency, a frame, a pair of wings converging therefrom, anadditional pair of wings spaced by the converging wings, each of saidwings being integral with a side of the frame, and therealong having aseries of ventilation openings with spaced hinge-providing portionstherebetween, and a peripherally inwardly flanged back interengagingwith such wings remote from the frame.

3. For a translucency, a frame, a pair of wings converging therefrom, anadditional pair of wings spaced by and forming angles in extending fromthe converging wings, each oi said wings being integral with a side oithe frame, there being nested arc stops abutting said angle to registerthe converging wings with the additional pair of wings.

4. For a translucency, a frame, a pair of wings converging therefrom, anadditional pair of wings spaced by the converging wings, each of saidwings being integral with a side of the frame, and a peripheralange-carrying back having offset arc stops to intert with complementarystops on the free ends of the wings with which the back is snapped intoassembly as a cap.
